Just to add, the vid shows analog dials. With the Icommand you don't get the lights. You'll know when you've hit winterization mode as it flashes up on the dials and the alarm sounds.
Another tip. I sealed-up my console and put one of those anti-damp silicon tray things in there. You can get them in in Woolworths. One will take a good litre or so of moisture out of the air.
